经过测试发现一个问题，使用USB供电是能识别到USB设备（Tina ADB能弹出来）。使用外部电源，把USB的电源断开就无法识别USB设备（Tina ADB不能弹出来）。

我发现了一个问题，我在上电后面刚识别设备时就点击固件烧录，可以进去烧录进度条。但是发现设备管理器里面弹出有不识别的设备。这个是不是就是烧录不进去设备没有识别呀。
有什么办法吗？

@whycan 在 V853 USB烧录不了问题—各位大佬帮忙看下 中说：
我记得只有安卓点这个地方才能进入烧录模式，你确认Linux可以这么做吗？
这个问题已经困扰我们太久了，还没有什么破解办法方法吗。

一、烧写问题描述：
-
1、USB上电后设备识别
-
2、PhoenixSuit.exe全志烧写工具识别
-
3、串口打印log

4、烧写失败
二、现象疑问 -
1、USB硬件上是从CPU——共模电感——USB连接器。没有发现硬件上的问题。
-
2、软件上使用同样的代码在双目开发板上没有问题，可以连接PhoenixSuit.exe烧录软件。
各位大佬，需要指点迷津呀，小弟在此谢过了。

@null037
兄弟，可以帮忙看下我这个问题吗？是不是也是芯片问题呀。这颗EMMC芯片也不在这个手册里面。[allwinner-v853-emmc-flash-support-list_v1.0.pdf]我这个开机打印没有你帖子里面的打印的内容多。

1、板子上面只有EMMC，没有TF卡和Flash其他的。
2、PC的启动顺序，我确认下。但是我用开发板插上USB是可以烧录看到进度条的。 -
V853 无法烧录问题@whycan晕哥发布在 V853系列-AI视觉
硬件背景
1、原理图参考官方双目开发板，电源管理使用 AXP2101。
2、EMMC使用妙存-AT70B08G3S03F。上电测试EMMC_CLK是50MHz波形。烧录操作
1、开机上电USB供电5V。
2、使用PhoenixSuit.exe软件烧录固件。3、附图烧录
4、附开机打印日志
开机打印.txt打印到最后就没有了。一直停在这个位置
